GENERAL SPECIFICATION FOR FIXING GLAZED CERAMIC FLOOR TILES OR  PORCELAIN TILES ONTO EXISTING FLOOR TILES ON INTERIOR SURFACE BEDS AND SUSPENDED SLABS

 

Please note that ‘general’ specifications are issued for information purposes, and should not be used as project specifications.  

As each and every project needs to be assessed individually on its own merits and characteristics please contact the  TAL Technical Advice Centrefor a project-specific detailed materials and methods specification for specific projects.

 

It is important that the tile selected is suitable for the application, preferably against a written Supplier’s specification.  Factors such as water absorption, irreversible moisture expansion, MOR and PEI ratings, chemical resistance and overall stability of the product need to meet the requirements of the service conditions.  

The backs of all tiles must be clean and free from dust and contaminants.

 

Please note that any “wet” areas, such as showers or balconies, should be waterproofed using 

TAL SUPERFLEX Ior TAL SUREPROOF waterproofing compounds prior to commencing tiling.  Please feel free to contact us for a specification for waterproofing and tiling these areas, as well as for technical literature on any of our products.

 

TAL PRODUCT REQUIREMENTS

The TAL products required for this installation are as follows:

TAL KEYCOAT
TAL GOLDSTAR 6
TAL BOND / TAL BOND POWDER
TAL WALL & FLOOR GROUT
NOTCHED FLOOR TROWEL
SPACERS
TAL SEALMASTER CORD
TAL GOLD STAR SEALMASTER 1000

 

Special note must be taken of the following:

Existing Tiles:

For this application it is imperative that the existing tiles are in good condition and firmly attached to the background, ie are not damaged, loose or hollow-sounding.  All cracked, damaged, loose or hollow sounding tiles must be removed prior to the new tile installation.

Adhesive System:

We have specified the use of TAL GOLDSTAR 6 rapid setting high strength adhesive for the installation of these tiles.  However, if timing allows for a quick-setting adhesive option, then TAL GOLDSTAR 12 can be considered.   

The advantages of using TAL GOLDSTAR 12 are as follows:

It is however important that newly installed tiles are protected from traffic (other trades, etc) for a minimum of 12 hours, while the adhesive sets.   This is especially important in fast-track installations.

Suspended Applications:

Tiling onto SUSPENDED concrete slabs require special precautions to be taken as the installation is prone to increased movement caused by slab deflection and creep, loading on the slab, etc. TAL BOND or TAL BOND POWDER needs to be incorporated in the adhesive and grout mix, or a single part flexible adhesive such as TAL GOLDFLEX needs to be used to allow for the increased movement.

NOTE: All Ground Floor levels with Basement / Parking levels below should be construed as SUSPENDED slabs.    

Tile Panel Movement Joints & Perimeter Joints:

It should be noted that the lack of movement joints in a tile panel, or poorly constructed joints,  is a major cause of tile failure.  Joints must be created at the required spacing and must be well raked out to remove all traces of adhesive residues, debris, contamination, etc, ie the joint must extend through the tile and tile adhesive layers. These joints must be filled with TAL GOLDSTAR SEALMASTER 1000 Polyurethane Joint Sealant (and suitable backing cord where applicable) in accordance with the manufacturer’s instructions.

(See later detail of correctly constructed tile panel movement joint and perimeter joint.)   

 

Should you require any further assistance or have any queries regarding the above, please do not hesitate to contact us.  Assuring you of our best attention at all times.  

 

Yours faithfully,
